AIRSPY R2 FREQUENCY CHANGES AFTER CENTERING

I'm not sure if this has been reported already and if it is a bug or such kind of oddity. So far I've seen it on the R2, the RSPDX which I use remotely doesn't show this behavior. The frequency of the radio (the real frequency, not what is shown by SDRC) changes after centering with the center funct...

Re: Moon

Well, I don't want push too much.

Step 1: Moonrise, Moonset at Home
Step 2: Elevation, Azimuth, Width, Delay, Self Dopler, Sun Elevation, Sun Azimuth at Home
Step 3: Same information for Stations or any point on the map (right click?)

Re: Moon

Maybe, between some toasts, a little bit of time to add MR/MS and moon projection.
Happy new year,

EME

Maybe nothing really exciting for some of you, but I wanted to share it anyway.
Last night I was able to receive 432 EME signals with an Airspy R2 controlled by SDR Console, feeding WSJT-X with the audio (no I/Q) from SDRC.

Re: 3D SOUND FOR CW (Maybe HRTF)

Pseudo stereo could be a starting point. The idea is to locate any signal in the given passband somewhere in the space, the center of the filter will be the center of the virtual space.
